Embodiments of the present disclosure provide a link adaptation feedback method, including: receiving, by a device, a link adaptation feedback frame sent by a communication peer end, where the link adaptation feedback frame includes a modulation and coding scheme request sequence identifier (MSI), where the MSI is configured to indicate space-time block coding type information.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A link adaptation feedback method, comprising: receiving, by a device, a link adaptation feedback frame sent by a peer end communications device, wherein the link adaptation feedback frame comprises a modulation and coding scheme request sequence identifier (MSI) comprising three bits, wherein one bit of the three bits in the MSI is used to indicate space-time block coding (STBC) information, and the space-time block coding information is used to indicate whether a data frame related to the link adaptation feedback frame uses space-time block coding.
2. The link adaptation feedback method according to claim 1 , wherein: when a value of the one bit is set to 1, it indicates that the data frame related to the link adaptation feedback frame uses the space-time block coding.
3. The link adaptation feedback method according to claim 1 , wherein: when a value of the one bit is set to 0, it indicates that the data frame related to the link adaptation feedback frame does not use the space-time block coding.
4. The link adaptation feedback method according to claim 1 , wherein the MSI is further used to indicate a link adaptation request.
5. A device, comprising: a receiving unit, configured to receive a link adaptation feedback frame sent by a peer end communications device, wherein the link adaptation feedback frame comprises a modulation and coding scheme request sequence identifier (MSI) comprising three bits, wherein one bit of the three bits in the MSI is used to indicate space-time block coding (STBC) information, and the space-time block coding information is used to indicate whether a data frame related to the link adaptation feedback frame uses space time block coding.
6. The device according to claim 5 , wherein: when a value of the one bit is set to 1, it indicates that the data frame related to the link adaptation feedback frame uses the space-time block coding.
7. The device according to claim 5 , wherein: when a value of the one bit is set to 0, it indicates that the data frame related to the link adaptation feedback frame does not use the space-time block coding.
8. The device according to claim 5 , wherein the MSI is further used to indicate a link adaptation request.
9. A link adaptation feedback method, comprising: sending, by a peer end communications device, a link adaptation feedback frame to a device, wherein the link adaptation feedback frame comprises a modulation and coding scheme request sequence identifier (MSI) comprising three bits, wherein one bit of the three bits in the MSI is used to indicate space-time block coding (STBC) information, and the space-time block coding information is used to indicate whether a data frame related to the link adaptation feedback frame uses space time block coding.
10. The link adaptation feedback method according to claim 9 , wherein: when a value of the one bit is set to 1, it indicates that the data frame related to the link adaptation feedback frame uses the space-time block coding.
11. The link adaptation feedback method according to claim 9 , wherein: when a value of the one bit is set to 0, it indicates that the data frame related to the link adaptation feedback frame does not use the space-time block coding.
12. The link adaptation feedback method according to claim 9 , wherein the MSI is further used to indicate a link adaptation request.
13. A peer end communication device, comprising: a sending unit, configured to send a link adaptation feedback frame to a device, wherein the link adaptation feedback frame comprises a modulation and coding scheme request sequence identifier (MSI) comprising three bits, wherein one bit of the three bits in the MSI is used to indicate space-time block coding (STBC) information, and the space-time block coding information is used to indicate whether a data frame related to the link adaptation feedback frame uses space-time block coding.
14. The peer end communications device according to claim 13 , wherein: when a value of the one bit is set to 1, it indicates that the data frame related to the link adaptation feedback frame uses the space-time block coding.
15. The peer end communications device according to claim 13 , wherein: when a value of the one bit is set to 0, it indicates that the data frame related to the link adaptation feedback frame does not use the space-time block coding.
16. The peer end communications device according to claim 13 , wherein the MSI is further used to indicate a link adaptation request.
